Parodinia costalis Coquillett. 



Syn. : Rhicnoessa costalis Coquillett, Proc. Wash. Acad. Sci., Vol. 3, 

 1 90 1, p. 378. 



Originally described from Galapagos Islands, and after- 

 wards recorded from Arizona by Coquillett (Jour. N. Y. Ent. 

 Soc., Vol. 10, 1902, p. 187), which record refers to the speci- 

 mens described below. To Coquillett's original description 

 of costalis it is necessary to add that there are five, not four, 

 pairs of dorso-central bristles. There is only one specimen 

 in the National Museum collection, which is not in very good 

 condition. 



Parodinia claripennis new species. 



Male. Opaque gray; anterior half of frons, antennae, except upper 

 surface of third joint, face, cheeks, proboscis and palpi, legs, except 

 fore femora, and halteres yellow. 



Bristling of frons normal; antennae of moderate size, third joint 

 distinctly longer than broad ; arista thickened at base, almost bare ; 

 cheeks about one-sixth as high as eye, marginal bristles of moderate 

 strength, vibrissa differentiated. Mesonotum with two rather faint 

 yellowish stripes close to, and between, the rows of dorso-centrals ; 

 about four irregular rows of discal setulae between dorso-centrals; the 

 pair of bristles between the posterior pair of dorso-centrals distinct ; 

 pleurae shining on lower portions, and with yellowish pollinosity on 

 upper half. Abdomen slightly shining; all segments with sparse set- 

 ulae on the surfaces and stronger post-marginal bristles. Legs with 

 fore femora blackened or browned, and sometimes the apices of fore 

 tibiae darkened also ; fore femora with 4 to 5 distinct bristles on apical 

 half of postero-dorsal and postero-ventral surfaces ; mid and hind 

 femora not so distinctly bristled; all- tibiae with distinct preapical 

 bristle. Wings clear ; veins brownish yellow ; second vein slightly un- 

 dulating ; veins 2-3 very distinctly divergent at apices, 3-4 distinctly 

 though slightly convergent. Length, 2-25/2 mm. 



Female similar in color, etc., to male. 



Type: Cat. No. 15,557, U. S. N. M. Locality: Williams, 

 Arizona (H. S. Barber). 



Paratypes : Williams, Bright Angel, and Flagstaff, Arizona, 

 same collector ; eight specimens. 



This species differs from costalis Coquillett, in having the 

 wings clear, the arista almost bare, and in being larger, as 

 well as in its much paler color. It is unfortunate that the 

 type of costalis is in such poor condition that the position of 

 the bristles cannot be definitely ascertained.
